基于Arduino的智能小车设计与实现

Design and implementation of smart car based on Arduino

为了提升智能小车的避障性能,文章设计了一种基于Arduino平台的智能避障小车,由超声波传感器、红外传感器、激光传感器构成多传感器自动避障系统。小车起步时,通过红外传感器判断是否前方有障碍物。小车行驶过程中,激光传感器完成前方较远距离障碍物信息采集,超声波传感器通过舵机的旋转,分别在左、前、右3方进行障碍物测距采集。综合分析两者信息,小车做出相应的避让动作。经实验验证,本小车能完成复杂障碍的自动避障。

In order to improve the obstacle avoidance performance of the smart car,this paper designs an intelligent obstacle avoidance car based on the Arduino platform.A multi-sensor automatic obstacle avoidance system composed of ultrasonic sensors,infrared sensors and laser sensors.When the car starts,the infrared sensor is used to determine whether there is an obstacle ahead.During the driving process of the car,the laser sensor completes the information collection of the distant obstacles in front,and the ultrasonic sensor performs the obstacle distance measurement collection on the left,front and right sides respectively through the rotation of the steering gear.Comprehensive analysis of the two information,the car makes the corresponding avoidance action.It has been verified by experiments that the car can complete the automatic obstacle avoidance of complex obstacles.
